TMS320C6A816x how to configure MPU clock frequency

damiano sartori

Hi,

currently the frequency core is set to 996MHz, and I want to set it at 1,3MHz. Which is the u-boot command to set the CPU clock at a new value?

best regards.

Damiano,

The current samples shipped from TI support ARM operation at 1GHz, and TI will provide an update when samples supporting other frequencies become available.

So can i just clarify that it is not possible to change the ARM clock on the C6A816x at this time?. Other posts have suggested that it is possible through u-boot. Can someone please clarify?.

Thanks,

Dave

Dave,

It is possible to change the ARM clock. We are preparing an app note that desribes how this is done.

Marc,

-Did that appsnote get written? Would be good to know how to safely switch gear on the fly (both ARM and DSP, or one of them).
